Microwave spectroscopic investigation of the Ne–acetylene van der Waals dimer
Bibliographic record
Abstract
Rotational spectra of eight isotopomers of the Ne–acetylene van der Waals dimer were measured in the frequency range of 5 to 23 GHz, using a pulsed molecular beam Fourier transform microwave spectrometer. Transitions within both the Σ0 ground state and the Σ1 first excited van der Waals bending state were measured for the isotopomers containing HCCH and H13C13CH, respectively. For the Ne–DCCD isotopomers, Σ0 and Π1 transitions were recorded, indicating a reversal of the energy level ordering upon deuterium substitution. The observed transitions indicate a Coriolis perturbation of the Σ1 and Π1 energy levels. The Σ1/Π1 state is no longer metastable for the Ne–DCCH isotopomers, so only ground state transitions were recorded. Nuclear quadrupole hyperfine structures were observed and partially resolved for isotopomers containing deuterium nuclei. The measured transition frequencies were compared to the values obtained by Bemish et al. from an ab initio potential energy surface using nuclear dynamical calculations. [R. J. Bemish, R. E.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
